Not sure if it was Robin Olds or Jim Boyd, both famous US Air Force fighter pilots, who said that swing-wing technology was a poor choice for fighter aircraft.
From the Wiki:
While variable-sweep provides many advantages, particularly in takeoff distance, load-carrying ability, and the fast, low-level penetration role, the configuration imposes a considerable penalty in weight and complexity. The advent of relaxed stability flight control systems in the 1970s negated many of the disadvantages of a fixed platform. No new variable-sweep wing aircraft have been built since the Tu-160 (produced until 1992), though it has been noted that the F-14's replacement - the F/A-18E - has a reduced payload/range capability largely because of its small fixed wings.
